Gakken Home Planetarium

Hobbyist self-assembly kit

Throw 10,000 bright stars onto the walls of your living room with the Home Planetarium kit by Gakken. Easy to assemble, the pinhole planetarium uses a small light bulb and a micro-perforated dodecahedron to cast the stars, galaxies, and constellations of the northern hemisphere onto your walls.

Three years in the making, the planetarium was designed using records from JAXA, a Japanese space and aviation research institute, to ensure high accuracy and a comprehensive collection of cosmic bodies. Kids love seeing their room covered in stars, but the planetarium also adds a very cool atmosphere to studies, living rooms, or bedrooms.
